A great game, although fairly easy.
-1.5 for being pretty easy, this problem would be solved almost completely if you didn't instantly respawn every time you died, with a small penalty of losing some money.
-1 for camera difficulties in co-op, which happens to be where the game is at its best. Split screen anyone?
Difficulty and time spent:
Takes a while to 100% which can keep even a hardcore gamer occupied for a while. However, to beat the main story only takes around one week, yet still retains replay value to collect new playable lego "figures", which is fortunate since almost everyone you see is playable at some point. This seems like a huge deal, but is made slightly less exciting by the fact that almost all the gunners, all the droids, and all the jedi/sith are about the same in every way but appearance.
Gameplay
In the latest Star Wars Lego game, you'll play as over 30 characters from the Star Wars saga in their brick forms, wielding light sabers via either the (rather unresponsive) wii motion controls or the 'B' button, while guns and droid effects can only be used with 'B'. You'll fight baddies which is fairly easy until you get swarmed by 5-10 battle droids. However, you'll just respawn as mentioned above. There are also some rather easy puzzles that seem like Zelda for children.
Summary
A great game overall, that could really be improved, possibly to a 9 or *maybe* a ten with some minor adjustments like not respawning, some differences between playable figures. I'd suggest looking into this game if you're looking for a stress-free Zelda type of game, or as a present for a 7-12 year old.
